Intrusion/Attack Detection
If the same IP address is accessed more than the specified number of times during a certain period, access from that IP
address is prohibited. In addition, IP addresses for which access is prohibited are managed as a reception refusal list,
and the reception refusal status is released (deleted) with administrator authority.
The IP addresses subject to the rejection are recorded in the audit log and sent to E-mail alert address lists 1 and 2 and
E-mail alert dealer address list.

SSL Settings
SSL can be used for data transmission over a network.
SSL is a protocol that enables the encryption of information communicated over a network. Encrypting data makes it
possible to transmit and receive sensitive information safely.
Data encryption can be set by the following protocols.
Server Port
• HTTPS: Apply SSL encryption to HTTP communication.
• IPP-SSL: Apply SSL encryption to IPP communication.
• Redirect HTTP to HTTPS in Device Web Page Access:
When this setting is enabled, all communication that attempts to access the machine by HTTP is redirected
to HTTPS.
If sending the e-mail fails, it will not be resent.
